Do I Need Corbels for Granite Countertops

Outdoor granite counters and bar tops need granite support corbels, legs, or brackets that are both weather resistant and able to support heavy loads.

Do you need support for granite overhang?

In most cases, support is placed underneath unless the overhang is 6 inches or less. According to the Marble Institute of America, you can safely overhang granite that is 1 ¼ inches thick up to 10 inches without support. However, the cantilevered portion cannot be more than one-third the total width of the countertop.

Does granite countertops need support?

Granite is very durable, so it will not easily crack or break, but granite countertops are typically between two and three centimeters thick. While this is thick enough for kitchen countertops, it requires proper support in all the right places.
